Convert a JavaScript statement to a string

I have an array in a variable like:

arr = [1, 2, 3]

How can I convert that statement to a string that it will be:

newArr = "arr = [1, 2, 3]"

Solution

  • Try this:

    const arr = [1, 2, 3];

const str = `${Object.keys({arr})} = ${JSON.stringify(arr)}`;

console.log(str);
